In 1944, as D-Day loomed, a Scottish mother of six stood trial at the Old Bailey under the Witchcraft Act of 1735. This deep dive unpacks the extraordinary collision of eras in the case of Helen Duncan, a physical medium who, armed with cheesecloth, egg whites, and a papier-mache mask, became a genuine concern for British national security.
